Baby quilts are some of my favorite things to make. I know that fun, unique quilt patterns for boys can be hard to find, so here are my favorite Scrappy Applique quilt patterns for little boys! (All Scrappy Applique patterns come in multiple sizes, so while some of these examples might be smaller, they can all be made into crib or lap sized quilts!)
Oh Deer
Lion Quilt
Dino
City Skyline
Wandering Bear Quilt
Robot Quilt!
All my patterns come in multiple sizes, so you can make these guys into a larger quilt.
I love these guys.
Tamed Fox
Pattern is in my book, Scrappy Bits Applique. 
Make him with or without the border.
Kraken
The mythical sea monster is too perfect for your little monster.
Phases of the Moon Quilt
Available in multiple sizes, including crib/lap.
For your little scientist.
Stormy Quilt
Pattern in my book, Scrappy Bits Appliqué.
I'm always adding new patterns-- are there any other images you think would be perfect for a little boy quilt?
